Question

What is the constant of proportionality? Y = -5x

Answer 1

`\huge\boxed{-5}`

The constant of proportionality can be found very easily in this example. Since
`x` and
`y` are directly proportionate, the constant of proportionality can be represented as
`r` in the following equation:

`y=rx`

Since the equation in the problem is given to us in this format, we know that
`r=\boxed{-5}`.
